Remember even as a kid wondering why they were doing these characters I'd never heard of when they were ignoring Mastermind, Mesmero, Living Monolith, Vanisher, Unus. etc... let alone dozens of other way better known, cooler Marvel bad guys.
I do think Comcast was eventually used some in Deadpool comics and not as a ridiculous joke character. Also, I believe he's been portrayed as being native to India. In that sense, Legends could stand to include some non-American/Canadian characters. I'd be all over the new foreign heroes introduced in the first Contest of Champions mini-series and subsequent creations like New Warrior's Timeslip (India), Egypt's Zephyr or Scarlet Scarab, England's Albion, France's Guillotine, Irish Wolfhound from Guardians of the Galaxy, Vormund (German) or some of the Japanese Big Hero Six.
